Final answer:
The total area of the composite figure is 231.68 yd².
Step-by-step explanation:
The composite figure can be divided into two parts: a rectangle and a triangle.
The rectangle has a base of 21.3 yards and a height of 12.8 yards, so its area is 21.3 yards multiplied by 12.8 yards.
The triangle has a base of 6.4 yards and a height of 14.9 yards, so its area is 1/2 multiplied by 6.4 yards multiplied by 14.9 yards. To find the total area, add the area of the rectangle and the area of the triangle.
Calculate the values and you will find that the total area of the figure is 231.68 yd².
